I have printed out info and studied the detail. I just can't see why a 2 speed pump won't be exactly what I need for my pool.

30k gal 60de filter and 1.5hp pump.

He tells me the pump's extra cost will not be worth it. He tells me that it won't make that much difference.

Why? I think I have explained to him why it is advantageous, but he tell me its not worth the extra money.

Anyone have any help or ideas here?
